Pneumonia severity index

The pneumonia severity index (PSI) or PORT Score is a clinical prediction rule that medical practitioners can use to calculate the probability of morbidity and mortality among patients with community acquired pneumonia.[1]

The PSI/PORT score is often used to predict the need for hospitalization in people with pneumonia.[2] This is consistent with the conclusions stated in the original report that published the PSI/PORT score:[1] "The prediction rule we describe accurately identifies the patients with community-acquired pneumonia who are at low risk for death and other adverse outcomes. This prediction rule may help physicians make more rational decisions about hospitalization for patients with pneumonia."[1]

Mortality prediction is similar to that when using CURB-65.[3]
